Last week, somehow my Klipsch Image S3 disappeared and obviously isn't coming back. I've been going around doing research on high quality IEMs for ~$50 (after LOTS of disappointments from generic brand IEMs) and came up with 3 candidates. The most important factors here are isolation and audio quality. So my three candidates are
1) Just buy another pair of Klipsch Image S3
2) Sennheiser CX300
3) Sony MDR NC13
Which of these do you think is the best choice?
I'm also open to other suggestions.
